The Breaking Point Applies to Magnum PI and to Oha Leechleaf Delissea

Summary: The Breaking Point applies to season 5 episode 2 Sunday, Feb. 19, 2023, of the action drama television series Magnum PI and to oha leechleaf delissea.

Boston-born Unitedstatesian botanist Horace Mann Jr. (Feb. 25, 1844-Nov. 11, 1868) acclaimed oha leechleaf delissea for "Petioles an inch long or less. Peduncles quite short. The persistent calux-lobes less than half a line long"; Sunday, Nov. 6, 2005, 10:52, image of Delissea rhytidosperma flower: Karl Magnacca (KarlM), CC BY SA 2.5 Generic, via Wikimedia Commons

The Breaking Point applies to season 5 episode 2 Sunday, Feb. 19, 2023, of the action drama television series Magnum PI and to the endemic, Hawaiian island-exclusive, Hawaiian island-only oha leechleaf delissea.

Director Bryan Spicer and writer Gene Hong bring multi-contextual breaking points into episode 78 overall and Magnum PI episode 2 on the NBC 2022-2023 television season. Breaking point connects life challenges, sustainability considerations and wave configurations respectively conducive to emotional and psychological chaos; non-survival/survival and extancy/extinction concerns; and surfing and swimming competitions. It describes oha leechleaf delissea whose International Union for Conservation of Nature designation determines the Hawaiian endemic (from Greek ἐν δῆμος, “in [with its] people”) super-threatened.

Two species of four Delissea-sectioned Hawaiian lobelioids earn the explanation “critically endangered” under the threatened conservation status of the International Union for Conservation of Nature (IUCN).

Horace Mann Jr., as scientific classifier of Delissea rhytidosperma (Jacques Delisse's wrinkled seed") in 1867, accredited oha leechleaf delissea as "A small tree, glabrous in all parts as far as known"; Sunday, Oct. 17, 2010, 15:56, image of foliage and fruits of Kaua'i delissea (Delissea rhytidosperma), endemic to Kaua'i, cultivated on O'ahu: David Eickhoff from Hawaiʻi, USA, CC BY 2.0 Generic, via Wikimedia Commons

Delissea argutidentata, Delissea kauaiensis, Delissea rhytidosperma and Delissea subcordata feature the Hawaiian name oha (from Hawaiian ōhā, “[name for Delissa-genused] lobelioid [subfamily member of bellflower family]”).

The Tracheophyte and Angiosperm (from Greek τρᾱχεῖᾰ φυτόν, “windpipe plant”; ἀγγεῖον σπέρμα, “receptacle seed”) clade members guard enclosed seeds and mineral-, nutrient-, sugar-, water-transporting vascular tissue. The Eudicot and Asterid (from Greek εὖ δι- κοτυληδών, “good two cup-shaped cavity”; and ἀστήρ, “star”) clade members have two embryonic seed leaves and star-like flowers. The Asterales order and Campanulaceae (from Greek ἀστήρ, “star” and Latin -ālis, “-related”; and Latin campāna -ula, “bell little” and -āceae, “resembling”) family members imitate bellflowers.

Oha leechleaf delissea, like three other Delissea species and unlike The Breaking Point on Magnum PI, journeys to the tipping point of species non-survival/survival, species extancy/extinction.

Horace Mann Jr., botanist through mentors Jean Louis Rodolphe Agassiz (May 28, 1807-Dec. 14, 1873) and Henry David Thoreau (July 12, 1817-May 6, 1862), acknowledged oha leechleaf delissea as acquiring "Leaves 3 to 5 inches long, 1 to 1[-]1/4 inches wide, thin and somewhat reticulated-veiny"; Monday, Feb. 21, 2011, 09:05, image of foliage of Kaua'i delissea (Delissea rhytidosperma), endemic to Kaua'i, cultivated on O'ahu: David Eickhoff from Hawaiʻi, USA, CC BY 2.0 Generic, via Wikimedia Commons

Habitat decrease, degradation and destruction kindle critically endangered Delissea argutidentata, kauaiensis and subcordata (from Latin argūti- dentāta, “clear-cut teeth”; kauaiēnsis, “Kauaian”; sub- cordātus, “below heart-shaped”) populations.

Delissea rhytidosperma (for southwest France-born Jacques Delisse, May 13, 1773-March 13, 1856; and from Greek ῥυτίς σπέρμα, “wrinkle seed”) likewise languishes from leveled, lost, lowered-quality habitat. The flowering plant, monitored taxonomically by Horace Mann (Feb. 25, 1844-Nov. 11, 1868), maintains itself in the wild by the many tiny seeds within its fruits. The wrinkled seeds nestle within berried, dark maroon to purple, fleshy, less or more globose (from Latin globōsus, “globular, rounded, spherical), small, 0.75-inch- (1.91-centimeter-) long fruits.

Wild Hawaiian occurrences, unlike The Breaking Point occurring in the urbanized Hawaii of Magnum PI, offers oha leechleaf delissea less opportunities to obtain extancy, survival occupancies.

Oha leechleaf delissea naturally adapts to rocky cliffsides whose moist forests admit Acacia koa (from Greek ἀκή, “sharp-pointed” via Greek ἀκᾰκίᾱ, “acacia”; and Hawaiian koa, “core, heartwood, ironwood, warrior”) as the dominant vegetation and woody plant. Horace Mann Jr. affirmed such an ambience when his new-species analysis allied oha leechleaf delissea with "Mountains above Waimea, Kauai"; Saturday, April 5, 2003, image of Hawaiian Islands endemic koa tree (Acacia koa), in habit, Makawao Forest Reserve, Upcountry Maui: Forest & Kim Starr, CC BY 3.0 Unported, via Wikimedia Commons

The near-2- to 10-foot- (0.61- to 3.05-meter-) tall oha possesses 5 to 12 green-white to purple- or violet-white, 1.5-inch- (3.81-centimeter-) long flowers black-maroon when fallen off.

Oha leechleaf delissea flowers quarter narrow, pointed, small petals and, June- through December-blooming before July- through January-fruiting, stamens queuing pollen onto the heads of nectar-feeding birds. Coarse, shrubby, sparse-branched stems retain black-green to green, 3- to 10-inch- (7.62- to 25.4-centimeter-) long, 2-inch- (5.08-centimeter-) wide leaves, sunlight-cast purple-red, with pointedly serrated, toothed margins. They seek filtered sunlight and well-drained soils in Acacia koa (from Greek ἀκή, “sharp-pointed” via Greek ἀκᾰκίᾱ, “acacia”; and Hawaiian koa, “core, heartwood, ironwood, warrior”) forests.

Annual-averaged 50- to 100-inch (127- to 254-centimeter) rainfall, 150- to 3,999-foot (45.72- to 1,218.89-meter) above-sea altitudes tender oha leechleaf delissea, like Magnum PI, The Breaking Point.

Private investigators Thomas Sullivan Magnum (Jay Hernandez) and Juliet Higgins (Perdita Weeks) go undercover as Robbie Perez and Jade Sanders, ostensibly transferred from Maui as relief lifeguards to eastern O'ahu's Sherwood Beach, in The Breaking Point, the second of the double-episode premiere of season 5 of NBC action drama television series Magnum P.I.: Magnum PI Headquarters @magnumpihq, via Twitter Feb. 19, 2023
